Hi BlueCodeExpress
thanks for your question.
Actually, there are things that you 'cannot do' is SSMS. Or better, you need to query system databases to retrieve them.
So, instead of googling them, it is much more comfortable to have a tool that contains most of them and visualize the results in a 'comfortable' way.
Moreover, based on the results of these queries, the tool will be able to suggest the user what to do.

Moreover, it is a better exercise for all of us, to understand how sql server works more deeply , and to automatize issues solving
